Reverse the provided string.

You may need to turn the string into an array before you can reverse it.

Your result must be a string.

`reverseString("hello")` should return a string.

```js
assert(typeof reverseString('hello') === 'string');
```

`reverseString("hello")` should return the string `olleh`.

```js
assert(reverseString('hello') === 'olleh');
```

`reverseString("Howdy")` should return the string `ydwoH`.

```js
assert(reverseString('Howdy') === 'ydwoH');
```

`reverseString("Greetings from Earth")` should return the string `htraE morf sgniteerG`.

```js
assert(reverseString('Greetings from Earth') === 'htraE morf sgniteerG');
```
